Abstract (en)

[origin: EP0062621A2] The invention provides a cutting insert for thread cutting operations of reversible type. The insert is prismatic in shape, one side surface of which being serrated so as to expose an even number of cutting teeth, the opposite side surface of which insert being intended as a side supporting surface. The insert is properly designed for grinding purposes and simultaneously enables stable clamping into a complementary shape of an insert receiving place of a toolholder, primarily because of two non-centrally passing clamp pin receiving bores.
